Turning centers


​Lathes and turning centers are manufactured to meet most industry needs.

The principle of lathes and turning centers is cutting a rotating component using a stationary cutting tool. The cutting tool moves parallel and perpendicular to the workpiece axis to provide the desired finished shape.

The turning centre has a choice of functions:

  • Horizontal and vertical design
  • Sub-spindle for two-sided machining
  • Driven tools
  • Y-axis for eccentric boring and milling
  • Several product ranges for multi-axis machine tools can provide turning results from roughing and grooving to threading and finishing.

 

     

    Quick change

    ​Less than 180º for clamping and unclamping.

     

    ​Short setup time

    Segment clamping makes it possible to change tools five times faster than with conventional tools.

    This means:
    • Higher machine tool utilization
    • Exact positioning
    • Few measuring cuts – improved profitability
    • Small batch production – quicker setup times
    • Few or no measuring cuts
    • Operations with frequent insert changes
    • Faster and efficient tool changing
    • Pre-setting possibilities.

    Insert change by using redundant tools

     

    ​Sister tools with Coromant Capto coupling.

    ​To maximize machine utilization, redundant tools can be changed quickly with the Coromant Capto system.

    • Less downtime – faster tool change
    • Inserts can be changed outside the machine
    • Stable cutting process
    • No risk of losing insert screws in the chip conveyer
    • Ergonomic
    • Easy to clean the tip seat and inspect the shim outside the machine.

     

    Automatic clamping units

     
    ​Automatic clamping units are used with all types of turning centers and vertical
    lathes with automatic tool changes.

    The units operate at pressures up to 1450 psi (100 bar).

     

    Static turrets

    Direct integrated turret

    ​Integrating the Coromant Capto system directly in turrets is the best solution for obtaining maximum performance out of the Coromant Capto coupling.

    • Short setup time.
    • Highest stability.
    • Faster tool change out than with conventional shank tools.
    • Cost effective solutions for many applications.
    • Minimized tool extension because the clamping mechanism is inside the turret. This provides the possibility for machining longer components.

     

    Conversion of standard turret to Coromant Capto® system

    The Coromant Capto system can also be integrated in existing turrets = using
    standard clamping units. A good alternative when direct integration is not possible (existing machines).

    Conversion of a standard turret to Coromant Capto system

    • No modification to the turret is needed and no special adapters are required.
    • Quick tool change resulting in less downtime.
    • Less stability compared to an integrated turret.
    • Takes more space than an integrated turret with the result that smaller components can be machined.

     

    Machine adapted clamping unit

     

     
    BMT
     

    A machine adapted clamping unit is a machine-specific Bolt-on Mounted Turret (BMT) unit. Due to the number of bolt-on designs, there are several types of units on the market which can be converted to Coromant Capto quick change system.

    Turret for driven tool holders

    ​Coromant Disc Interface (CDI)

     

    CDI

    ​The Coromant Disc Interface (CDI) functions between the turret and the clamping units.

    Compared to a regular “bolt-on” style (BMT) or Vertical Disc Interface (VDI), the CDI offers several advantages:

    • High stability and rigidity.
    • Identical interface for static and driven tool holders.
    • Flexible and symmetric interface (180º mountable).
    • Centerline adjustment for right-angle tool holders.
    • Shorter tool projection resulting in longer tool capabilities.

    Coromant Capto® system for VDI turret

     

    VDI

    ​The Coromant Capto system can be used with a clamping unit as a quick change system in a VDI adapted turret.

    • Intended both for driven and static tools.
    • Camshaft activated.
    • Change cutting tools outside the machine.
    • Off-line pre-setting outside the machine.
    • External coolant.
    • Less stable compared to CDI.
    • Clamping mechanism is not built in the turret - longer tool projection.
